How do I fix root rot in my Heath speedwell?

Root rot happens when the roots sit in soggy soil for too long, preventing them from getting oxygen. Check the roots immediately if the plant looks yellow or mushy at the base.

Check these first

  1. Smell the soil for a musty or rotten odor.
  2. Check if the pot has drainage holes.
  3. Gently lift the plant to inspect the roots for a slimy, dark appearance.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The soil stays constantly wet and smells slightly sour or swampy. The base of the stems may turn brown or mushy.

    What to do: Stop watering immediately and let the soil dry out. If the damage is severe, repot the plant into fresh, well draining soil after trimming away black, slimy roots.

  2. Poor Drainage

    Possible

    How to tell: Water pools on the surface of the soil for a long time after watering. The pot lacks holes or the soil is too dense.

    What to do: Ensure the pot has drainage holes at the bottom. Use a potting mix amended with perlite to improve airflow to the roots.

When to worry

If the roots are black, mushy, and falling apart, the plant is in critical condition. If they are still firm and white, you can save it by adjusting your watering.

Stopping it coming back

Always check that the top inch of soil is dry before watering again. Use a pot with drainage to ensure excess water can escape.

Questions people ask

Can I save a plant with root rot?
Yes, if you catch it early. Trim the dead roots, repot in fresh soil, and be very careful not to overwater while it recovers.
How often should I water to prevent rot?
Stick to a rhythm of every 3 to 7 days, but always use the finger test. If the soil is still damp after 7 days, wait longer.
